An Anonymous Message Board Where Everything Disappears
No account. No username. No followers. You write something. It lives for 24 hours. Then it is gone.
Letheca is a browser-based anonymous message board for brief, unfiltered expression without a permanent profile attached to what you say.
There is one exception: if a post earns enough echoes, one sentence survives as a Ghost Trace in the public archive.
How It Works
- Open the board with no signup.
- Write something up to 500 characters.
- Others can echo what resonates.
- After 24 hours, the post vanishes.
- If echoes cross the threshold, one sentence survives forever.
What Letheca Is Not
- Not a chat app with DMs or reply chains.
- Not a social network with profiles and followers.
- Not permanent by default. Disappearing is the rule.
